What is the best hard drive based player?


Looking for a hard drive based player to feed into my system....preferrably one that has lots of memory, good sound quality, good user interace but does not require a separate screen. Any suggestions?

The Yamaha can be tuned, too, as is done in Germany by Manfred Diestertich, chief of Audio Physic. It comes to 1650 Euros in this version, and sonically very close to the much more expensive McIntosh - at least this was the conclusion of German Stereoplay, when comparing these units recently. And there seems to be another quite interesting unit from British Zero One, see an essay-review on

How does an IPOD (with Apple lossless compression files) feeding into the main system compare to such hard disk drive players in terms of sound quality?
